so i just got an M-audio Sonica theater card, and it does up to 7.1 surround sound through 4 mini-jacks (1/8"). My question (one which may pertain to people using onboard 5.1 sound too) is in regards to the center/sub line. I am going to be running 4.1 surround, with the 4 channels going to FR, FL, RR, RL and the sub line going to my amp in the trunk.
When i plug a mini-jack into the center/sub line, how do i know which one is going to put out the sub line?
Im assuming there is a difference between center out and sub out :) Also, my sub line would be a mono out (1 RCA plug), but my current amplifier (though it is a mono amp) takes 2 rca inputs. should i just split the mono line out into stereo sound at the soundcard and run stereo wires back there to the amp?
For those curious i am running a cadence A7+HC amp with a JL 12W6v2.
Thanks for the input.
